No politics just science

There are many interfaces between medical science and chemical technology. At those crossroads between different disciplines the most unexpected developments often occur. In the chemical industry, we make a risk analysis to describe and assess all possible scenarios based on possible occurrence (frequency) and their consequences (the effect). Applying a Covid risk analysis to the infection risk due to transmission and extensive study of scientific literature provided some useful insights and assumptions:

The risk of infection can be reduced by

  • reducing the viral load in the mucus
  • reducing the residence time of infectious viruses in the mucus
  • and by diminishing the infectious nature of the viruses in the mucus.

Proven scientific knowledge by experts in the field

Known data prove that free copper ions in the mucus damage bacteria and viruses on site. Whereas intact bacteria and viruses can stay undetected, damaged bacteria and viruses are immediately recognized and attacked by the innate immune system in the mucus of the upper respiratory area.

The obvious conclusion: a very pure copper thread in contact with the mucus in the nose should reduce the number of bacteria and viruses in the mucus of the nose and throat and thus the transmission. Hence the NPPU can help reduce the spread of respiratory syndromes such as COVID-19.

The NPPU was developed on the basis of literature research, including physiology, immunology, nutrition, toxicology, technology and patents, our specific knowledge regarding the use of essential minerals in water (Water & Minerals Advice) and an executed infection by transmission risk analysis.

Initial tests with the cooperation of Maastricht University have shown that the bacterial load is demonstrably reduced by wearing the NPPU temporarily (2 to 8 hours/day).

Opportunities to carry out tests on transmission reduction in some townships in South-Africa were briefly explored by Maastricht University. This would include the necessary essential steps, such as the registration of the NPPU, the notification of ‘medicinal intervention’, an approval of an ethics committee and the acquirement of the necessary financial support; all of which would take a long time and involve many experts, who are not yet available to us.

What experts say about the development status of the NPPU


The effectiveness of the NPPU to reduce the infectious bacteria load in the mucus is theoretically and practically proven.


It is theoretically known that bacteria and viruses are killed and damaged by the use of copper.


Not yet proven is the efficiency of the elimination of viruses by copper ions in the mucus although in the first investigations the reduction of bacteria is proven and therefore the reduction of viruses seems plausible.


Not yet proven is the possible short- and long-term negative health impact by wearing the NPPU, although unlikely based on literature and concentration measurements.
